Parameter
| Biomarker | CEA (carcinoembryonic antigen) | Full name | Carcinoembryonic antigen | Molecular Type | Protein |
|---|---|---|---|---|---|
| Molecular Formula | Molecular Weight | Core Functional Dimensions | Monitoring, prognosis | ||
| Disease | Colorectal Cancer (CRC) | Disease Subtypes | / | ||
| Organ | Colorectal | Test Sample / Technology Platform | Blood (ELISA, chemiluminescence immunoassay) | ||
| Pathobiological Mechanisms | The expression is low in normal adult tissues and abnormally elevated in CRC, and is involved in tumor cell adhesion and invasion | ||||
| Clinical Availability Status | Clinically available (monitoring) : It is routinely used to monitor postoperative recurrence of CRC and is not recommended as a screening marker | ||||
| Notes and Dynamics | Low specificity, easily influenced by factors such as smoking, inflammation, should be combined with other markers to improve diagnostic accuracy | ||||
